Posted up in the Audio forum,but things are a little slow over there and I need a replacement today. I've done a search on this issue I just need answers about the car sitting for a couple weeks at a time with the alarm armed. Thanks

 

I have had the same battery in my R for about 2 weeks. It's sat for about a week and a half under the cover and cranked fine when I drove it. I too have an alarm, and was armed the entire time. Hope this helps. Also http://www.parkeryamaha.com seemed to have the best price; about $70.
